SPECIFICATIONS. Specifications describing certain Improvelnents in Tuck-Markers for Sewing-Machines,

invented by RICHARD Gr. BUSH, of J amestown,'

in the county of Chautauqua and State of New York.

The object of my invention is to produce a simple and efficient device for creasing the goods while one tuck is being sewed; and consists in the combination of a vibrating slotted cloth-presser located under the presser-foot of a sewing-machine, with a stationary point on the bed of the tuck-marker, and a vibrating arm that is .operated by the needle-bar.

The accompanying drawing is a perspective View of the invention.

vA is the bed of a tuck-marker, made of thin spring metal, of which B is the slotted vibrating cloth-presser, and C is the stationary point over which the goods pass. D is a vibrating arm, which is operated by the needle-bar of a sewing-machine through the slot a, and ismade to yield or spring more readily by being curved, as shown at F f. The tuck-marker is attached securely to the bed of a sewing-machine by means of a common gaugescrew passing through the gauge d, in such a manner that the needle will pass through the slotI in the vibrating arm D and the slot in the vibrating cloth-presser B.

In practical operation the goods to be tucked are folded the iirst time, and placed over the bed A and lip C, and under cloth-holder g and vibrating cloth-presser B, back against the gauge d, (which may be set for any desired width of tuck,) and the presser-foot of the Inachine let down on the cloth-presser B. Now, as the needle descends to its lowest point, the feed drops below the cloth-plate of the machine, and the vibrating cloth-presser holds the goods rnily on one side of the lip C, while the vibrating arm presses the goods on the other side, thereby making a distinct crease,

and as the needle and feed raise to their highest points, the goods are released and fed through without drawing.

I clailn- The combination of the slotted vibrating cloth-presser B, through which the needle operates, with the lip Cand the vibrating arm D, all constructed, arranged, and operating as and for the purpose described.
